Adolfas Jucys
Adolfas Pranaitis Jucys (12 September 1904 – 4 February 1974) (also referred to as ''Yutsis'', ''Yuzis'', or ''Ioucis'' depending on translation) was a Lithuanian theoretical physicist and mathematician, and inducted member of the Lithuanian Academy of Sciences in 1953. He graduated from Kaunas University in 1931 and later worked with both creators of the self-consistent field method – Douglas Hartree in Manchester (in 1938) and Vladimir Fock in Leningrad (1949–1951). Adolfas Jucys created the scientific school of theoretical physics in Vilnius, was the head of the Department of Theoretical Physics at Vilnius University (1944–1971). He organized the first Institute of Physics and Mathematics in Lithuania and was its first director (1956–1963), and later (1971–1974) the head of the Institute's Department of Quantum Mechanical Calculations. Jucys developed the theory of the electronic structure of atoms, formulated in a general form the multiconfiguration Hartree–Fock e ...

Table Of Simple Cubic Graphs
The connected 3-regular (cubic) simple graphs are listed for small vertex numbers. Connectivity The number of connected simple cubic graphs on 4, 6, 8, 10, ... vertices is 1, 2, 5, 19, ... . A classification according to edge connectivity is made as follows: the 1-connected and 2-connected graphs are defined as usual. This leaves the other graphs in the 3-connected class because each 3-regular graph can be split by cutting all edges adjacent to any of the vertices. To refine this definition in the light of the algebra of coupling of angular momenta (see below), a subdivision of the 3-connected graphs is helpful. We shall call * Non-trivially 3-connected those that can be split by 3 edge cuts into sub-graphs with at least two vertices remaining in each part * Cyclically 4-connected—all those not 1-connected, not 2-connected, and not non-trivially 3-connected This declares the numbers 3 and 4 in the fourth column of the tables below.

Vytautas Magnus University Alumni
Vytautas (c. 135027 October 1430), also known as Vytautas the Great ( Lithuanian: ', be, Вітаўт, ''Vitaŭt'', pl, Witold Kiejstutowicz, ''Witold Aleksander'' or ''Witold Wielki'' Ruthenian: ''Vitovt'', Latin: ''Alexander Vitoldus'', Old German: ''Wythaws or Wythawt'') from the late 14th century onwards, was a ruler of the Grand Duchy of Lithuania. He was also the Prince of Grodno (1370–1382), Prince of Lutsk (1387–1389), and the postulated king of the Hussites. In modern Lithuania, Vytautas is revered as a national hero and was an important figure in the national rebirth in the 19th century. ''Vytautas'' is a popular male given name in Lithuania. In commemoration of the 500-year anniversary of his death, Vytautas Magnus University was named after him. Monuments in his honour were built in many towns in the independent Lithuania during the interwar period from 1918 to 1939. It is known that Vytautas himself knew and spoke in the Lithuanian language with Jogaila ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Symmetric Group
In abstract algebra, the symmetric group defined over any set is the group whose elements are all the bijections from the set to itself, and whose group operation is the composition of functions. In particular, the finite symmetric group \mathrm_n defined over a finite set of n symbols consists of the permutations that can be performed on the n symbols. Since there are n! (n factorial) such permutation operations, the order (number of elements) of the symmetric group \mathrm_n is n!. Although symmetric groups can be defined on infinite sets, this article focuses on the finite symmetric groups: their applications, their elements, their conjugacy classes, a finite presentation, their subgroups, their automorphism groups, and their representation theory. For the remainder of this article, "symmetric group" will mean a symmetric group on a finite set. The symmetric group is important to diverse areas of mathematics such as Galois theory, invariant theory, the representatio ...
